Designed to improve students' thinking, learning, and creative skills while they learn to program a microcomputer in BASIC programing language, this instructional manual for advanced learners provides a brief section of information for each new topic together with a sample program to enter, run on the computer, and observe; a suggested change to clarify the principle being taught, and a challenge requiring use of the new principles. Each chapter includes a review. The following commands are taught in this volume: GET N$, ASC(N$), LEFT$(X$,N), RIGHT$(X$,N), MID$(X$,J,N), LEN(N$), VAL(X$), STR$(X), ONERR GOTO, PEEK(X), and POKE X,Z. A reference chart displays commands and their functions. Separate color coded project books for junior high and high school/adult students are available for this manual. (Author/LMM)
